Extend the wire into the wire slot 33, align the wire with the card slot 41, and fasten it into the card slot 41 from bottom to top. Then rotate the handle 10, the handle 10 drives the gear 17 to rotate, and the gear 17 drives the first A disk 42 rotates, and the first disk 42 drives the winding groove 43 to wind the wire to collect the wire. It does not need to be manually fixed during winding, and the operation is simple;

When you need to loosen the wire, press the gear 17, the gear 17 drives the spline shaft 19 to slide down, the spline shaft 19 drives the first disk 42 to slide down, and the first disk 42 slides down to make the internal ratchet teeth 45 and the pawl 46 is disconnected. At this time, the first disc 42 can be rotated in the reverse direction, that is, the wire is pulled to make the winding groove 43 reverse to loose the wire. When the cable is loosened and pressed, the hub plays the role of wire gathering again.

To sum up, the multifunctional hub of the present invention is simple and clear in operation, sensitive in response, time-saving and labor-saving; meanwhile, the device of the present invention is rich in functions, firmly fixed and practical.
